description |
There are several bugs affecting Broadwell generation graphics in the vivid kernel (3.19), but not found in 4.2rc which i915_bpo module is based on. In order to support our OEM partners (and other BDW users) it would make sense to migrate BDW to use i915_bpo instead.
The known (public) bugs this would fix are:
- screen is black after xrandr rotate command
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1446979
- changing the VT causes flicker
https://bugs.freedesktop.org/show_bug.cgi?id=85583
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1472070
- GPU hangs on resume
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1468232
(and dupes, which I believe there are several of)
- and some OEM machines can't always hotplug the HDMI output (no public bug AIUI)
the migration should not be too risky, since i915_bpo is already used for Braswell which is same generation as (=based on) BDW. |
